Abstract: Due to the rapid development of mobile communication technologies, several applications are proposed on the mobile devices. We present a novel and low-computation E-cash transfer system to prevent blackmail for mobile communications. Our proposed protocol is based on a session key with mutual authentication, a digital signature and a public key system. In our system, the problematic account designated by the criminal is able to be traced under the blackmail.

Keywords: electronic cash; blackmail; low computation; mutual authentication; mobile communications; cryptography; security; e-banking; digital signatures; public key; e-cash transfer; electronic banking; online banking; cyber crime; online cash transfer.
